When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits.
310 × 20 = 6200
6200 already has two significant digits.
The two.
Two. The decimal indicates that the zero is significant otherwise it wouldn't be a significant digit.
62 is 20 percent of 310.
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.
To determine how many times greater the boxed digits on the left are than those on the right, you would divide the value of the left boxed digits by the value of the right boxed digits. For example, if the left boxed digit is 20 and the right boxed digit is 5, you would calculate 20 ÷ 5 = 4. Therefore, the left boxed digits are 4 times greater than the right boxed digits. Please provide the specific boxed digits for a precise calculation.
The two.
310+205 of 310=310+ 20/100*310=310+62=372
Significant digits refer to the number of digits that are known versus the number of digits that are estimated. So if the number 20 is an approximation, there is only one significant digit, which is the 2. However, if 20 is accurate to the ones place, then there are 2 significant digits. 20.00 has four significant digits, because it is known that the number is accurate down to the hundredths place.
Two. The decimal indicates that the zero is significant otherwise it wouldn't be a significant digit.
0.20 X 75.00 = 15, to the justified number of significant digits.
62 is 20 percent of 310.
310-20=290
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.

The number 20 can be expressed in significant figures depending on how precise you want it to be. If it is written as "20," it has one significant figure. If you want to indicate that both digits are significant, you can write it as "20." or "2.0 x 10^1," which shows two significant figures. The use of a decimal point or scientific notation clarifies the number of significant figures intended.
The proposition is false. From 1 to 99, the digit 0 is NOT repeated 20 times!
